ZZZ 199 2246
A: Hi ML. The FCM Accessory tray (model ZZZ 199 2246) is designed for the FCM 2246 skylight. The FCM 2246 Accessory Tray requires a minimum opening of 21-1/8" X 45-1/8". As long as your FCM finished opening is slightly larger than 21-1/8" X 45-1/8", the ZZZ 199 2246 Accessory Tray should fit.
A: Yes, this will work for an older FCM (fixed curb mount) Skylight. Thank you.
A: If you have built the curb for the skylight to the dimensions specified by Velux for the skylight, which I think is about 49 1/2" x 25 1/2" for the 2246 skylight, then the assembled frame will fit precisely over the outer edge of the skylight curb. It comes complete with the pick and click tabs.
A: First, you should see a link towards the bottom of the web page that says "downloadable PDFs." This should get you what you need in regards to installation. Second, your question requires a two-fold answer. If you order a FCM skylight with a blind "factory-installed," then the accessory tray comes pre-assembled with the blind installed. If you order the accessory tray by itself, then you will have to put it together. It does come as 4 pieces and the pick-and-click brackets are pre-installed. The accessory tray is designed to sit down on the curb and "hang" inside the opening. It becomes like a skylight frame. The accessory tray, therefore, requires a certain inside dimension for it to fit down into. We would be glad to supply you with our accessory tray minimum dimensions chart if you call us at 800-888-3589. We can also answer any other questions you may have.
A: The accessory tray is made of a fiber glass material.
